CMake Warning (dev) in CMakeLists.txt:
  No cmake_minimum_required command is present.  A line of code such as

    cmake_minimum_required(VERSION 2.8)

  should be added at the top of the file.  The version specified may be lower
  if you wish to support older CMake versions for this project.  For more
  information run "cmake --help-policy CMP0000".
This warning is for project developers.  Use -Wno-dev to suppress it.

With autotools I get this:

jonquil@jonquil-Satellite-L755D:~/Downloads/akonadi-googledata-1.2.0/build/build$ autoreconf -i -f
Can't exec "libtoolize": No such file or directory at /usr/bin/autoreconf line 196.

autoreconf: `configure.ac' or `configure.in' is required

  1. Install build-essential Install build-essential if you haven't done so already. You can install it in the Software Center or with:

    sudo apt-get update && sudo apt-get install build-essential

  2. gcc does not contain g++, these are different packages. Install g++ Install g++:

    apt-get install g++

  3. I am aware that this is "Ask Ubuntu", but if someone with Fedora would meet this problem, the following helped me:

    sudo dnf install gcc-c++
